Description

[Detailed description of the invention] The present invention is provided with a rotating seedling feeder in which seedling locking protrusions are formed at appropriate intervals in the circumferential direction and protrudes upward from the seedling placement surface of the seedling placement stand. The purpose of the seedling supply device is to have a simple structure and to facilitate the operation of supplying seedlings.

Embodiments of the present invention will be described in detail below based on the drawings.

As shown in FIGS. 1 to 4, it is equipped with left and right front wheels 1, 1 that can be operated to change direction and rotate for driving, left and right rear wheels 2, 2 that can be rotated for driving, a front engine 3, a driver's seat 4, etc. At the rear of the vehicle body, there is an inclined seedling platform 5 which is driven laterally reciprocating at a constant stroke with six pine-shaped seedlings W placed side by side in a horizontal direction, and a slanted seedling platform 5 which is driven to reciprocate horizontally at a constant stroke with six pine-shaped seedlings W placed side by side. Six planting claws 6 that sequentially take out and plant seedlings one by one from the lower end..., projecting upwardly from the seedling placement surface S of the seedling placement platform 5; Each of the pine-shaped seedlings W is locked and sent to the lower end by seedling locking protrusions 7a formed at appropriate intervals in the circumferential direction and driven and rotated by a constant angle each time the seedlings W reach the stroke end. A seedling planting section equipped with a plurality of rotary seedling feeders 7, three soil leveling floats 8 arranged side by side at appropriate intervals in the lateral direction, etc.
It is connected via a four-link mechanism 10 that can be raised and lowered relative to the vehicle body using a hydraulic cylinder 9, and is configured to automatically and continuously plant six seedlings one after another as the vehicle advances. The structure is such that the seedling planting section can be raised and lowered in order to maintain a constant planting depth regardless of variations in the amount of seedlings sunk into the mud.

As shown in FIGS. 1 and 2, the driver's seat 4
In front of the engine 3 and on both sides of the engine 3, there are provided spare seedling resting frames 11, 11 for accommodating the spare seedlings Wa in three tiers above and below, and between the driver's seat 4 and the seedling resting stand 5. , a pair of left and right spare seedling stands 12, 1 on which three spare seedlings Wa... can be placed horizontally side by side.
2 is provided so as to be swingable forward about the vertical axis X and swingable up and down about the horizontal axis Y in order to receive the spare seedlings Wa stored in the spare seedling holding frames 11, 11. The structure is configured such that 12 spare seedlings Wa can be equipped to be supplied to the seedling rack 5, and the spare seedlings Wa stored in the spare seedling rack 11 can be installed.
The structure is such that after the Wa is once transferred to the preliminary seedling rack 12, it can be supplied to the seedling rack 5 from now on.

As shown in FIGS. 3 and 4, the working position is located above the outer circumferential locus of the seedling locking protrusion 7a of the seedling feeder 7, that is, the operating locus of the seedling locking protrusion 7a of the seedling feeder 7. A leaf spring 13 as a seedling guiding tool which can be deformed and returned to its original state is provided with its lower end fixed to the lower surface of the seedling stand 5 with a pin, and the leaf spring 1
3 at the upper end of the seedling feeder 7 against the return biasing force;
In other words, the rod-shaped operating tool 14, which is held in a non-working position located below the working locus of the seedling locking protrusion 7a of the seedling feeder 7, is detached from the locking frame 15 fixed to the lower surface of the seedling rest 5. The leaf spring 1 is operable when supplying seedlings to the seedling stand 5.
3 to the operating position, the seedlings can be guided in a detour above the seedling feeder 7.

In addition, to implement this proposal, multiple seedling feeders 7 are required.
All of the seedling guide tools 13 provided correspondingly to each
It is convenient to configure the device so that it can be switched between the working position and the non-working position at once using a single operating tool.

The seedling guiding tool 13 may also be of a different configuration, such as one configured to switch between an active position and a non-active position by swinging the seedling feeder 7 around its rotational axis, as shown in FIG. 5, for example. There are various possibilities.

In summary, in the seedling feeding device according to the present invention, the rotary seedling feeder 7, in which the seedling locking protrusions 7a are formed at appropriate intervals in the circumferential direction, is made to protrude upwardly from the seedling placing surface S of the seedling placing table 5. In the seedling feeding device provided in the above-mentioned state, a seedling guide device 1 guides the seedlings by detouring above the action locus of the seedling locking protrusion 7a of the seedling feeding device 7.
3, and the seedling guiding tool 13 is extended from the upper side to the lower side in the seedling feeding direction with respect to the seedling locking protrusion 7a of the seedling feeder 7 that protrudes above the seedling placing surface S. It is provided so as to be switchable between a working position located above the working locus of the seedling locking protrusion 7a and a non-working position located below the working locus of the seedling locking protrusion 7a of the seedling feeder 7. It is characterized by

That is, when replenishing the seedling tray 5, the seedling guide 13, which guides the seedlings in a detour above the seedling feeder 7, is switched to its working position, thereby preventing the seedlings from being unnecessarily latched to the seedling feeder 7. This makes it possible to easily carry out seedling replenishment work while avoiding the inconvenience of being subjected to resistance to movement or being damaged. Further, the present invention has great advantages in terms of practical manufacturing, since it achieves the desired purpose by providing a seedling guiding tool 13 that can be easily constructed.
To elaborate, as an alternative means of achieving the purpose of the merits,
A possible method is to provide the seedling feeder 7 so that it can be switched between an active position in which it protrudes upwards and a non-active position in which it is retracted downward relative to the seedling resting surface S of the seedling resting table 5, but in the case of this means, Although it is necessary to configure the drive mechanism of the seedling feeder 7 to allow changes in attitude, and the overall structure becomes expensive, the present invention can be easily implemented without such disadvantages.

Incidentally, although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
